Thermostat
Which one should I get ? It is a daily driver and I do use it in the winter...
so... 160 or 180 degree ? pros and cons of both ? |
i always get 160*'s whever possible...the only downside to 160*'s is in the winter the car might not warm up very quickly meaning no heater for 10 or so minutes. Tuning is usually smart though otheriwse your stock fans dont come on till 226* ;)
|
i would replace it anyways... my stock thermostat used to get sticky and not open sometimes
|
Yea I was planning on getting a tune after I get the car inspected in June sicne my warranty is up( and I want to add a few more goodies before tune), and I plan on ordering the manual switch for the fans for when i'm at the track.

160*. I run mine year round and yea, gotta wait a little bit for heat in the winter but no big deal IMO.

Hey, isnt your car missing some of its interior?? Why worry about heat? lol
My third gen had a 160 in it, heat always worked good. just have your fans programmed to come on at a higher temp in winter, if they even come on at all that is. |

ive read that a lower temp thermo can actually be bad in some cases, because new engines are designed to heat up the oil to where condensation in the oil will evaporate and not stay in the oil contaminating it. also that it can be bad because cylinder are meant to be a certain temp for propper combustion and if u lower that temp it can soak up to much of the heat and prevent it from completely burning the fuel goin in then eventually making your cats go bad if u have them. i would guess with tuning that would be avoided probably but it was somehtin i read if i can find the link ill post it. vinci high performance wrote it
edit: i found it here read this its pretty interesting. Quote:

good read but this part "One final point - running a computer managed engine at 165°F compared to the factory 210°F will often cost you as much as 4 MPG. The reason for this is that the computer thinks that the engine is not off the “choke cycle” and it is still putting out a rich mixture!" is complete bs in all vehicles I've ever tuned. Most tunes command that if the iat temp is over 14*F and the ECT is over 92*F the car will go into closed loop which commands 14.6-14.7:1 a/f ratio.
|
good to know, just thought id throw that in, but the oil contamination i would think could be tru and the heat soak of the cylinders correct?

like I said, good read...just pointing out known misinformation in it. |
ok sounds good lol
|
Do you realize that with your LS1 there is a "free mod" that allows you to adjust the temperature of the stock thermostat?

Please, enlighten me my friend. how can this be done? |
:confused:
|
I assume hes referring to drilling the stock tstat.
|
No drilling.... you shim the t'stat spring with a brass ferrule...... its covered in the Chris Endres "Chevy LS1/LS6 Performance" book. I could send you a copy of the page if you want. The LS1 'stats are expensive, because they include the complete "housing":

Hey since this discussion has something to do with a problem im having and foff667 is a tuner extrordinare... my 93 LT1 bird will not turn either cooling fan on no matter what. ive replaced the coolant temp sensor in the water pump, replaced the relays, i have voltage at the relay block. i have to turn the fans on manually with my home made switch. i have a 160 stat and a pcmforless chip with programming for the stat. is there anyway that a power spike or anything could have "erased" the fan programming from my tune? they dont even come on at the factory setting. i dont know what else to check thats why im thinking maybe something went wrong with the chip, if its possible.

:shrug: i remember eric had some issues with his 93 when he first bought it as well...not sure what the fix was though.
|
how bout that page for us to read, im curiosu mself
|
were can I get all the ls1 free mods? like not get them but read about all of them, Id like to know just for my own information cause Ill be getting one some day
|
i believe the webpage is called "install university" google it....
|
that would be www.installuniversity.com & www.ls1howto.com
|
I was searching for some info on which temp thermostats work best. I'm especially interested in a boosted car, stock 195 or a 160 degree stat. Any dyno proven results? I know this is an old thread, anyone still running the 160 degree stat?
